Using Python 3 + Google Cloud Vision API's OCR to extract text from photos and scanned documents

Just a quickie test in Python 3 (using Requests) to see if Google Cloud Vision can be used to effectively OCR a scanned data table and preserve its structure, in the way that products such as ABBYY FineReader can OCR an image and provide Excel-ready output.

The short answer: No. While Cloud Vision provides bounding polygon coordinates in its output, it doesn't provide it at the word or region level, which would be needed to then calculate the data delimiters.

On the other hand, the OCR quality is pretty good, if you just need to identify text anywhere in an image, without regards to its physical coordinates. I've included two examples:

####### 1. A low-resolution photo of road signs

These are notes while researching a way to convert a browser/website to a stream. This could be used for Facebook Live or for webrecording. TL'DR:

I started with Phantomjs - but that didn't support the html5 video tag
SlimerJS supports it, but there is no way to record audio directly (though this might come from desktop audio)
So I moved to research ffmpeg/X11/XVFB to record it with linux which works
But ffmpeg has no easy way to mix streams/overlays to I moved on to OBS with overlay browser support
I started researching options OBS in docker and it needed best a GPU , so I move to nvidia-docker
And so came across building game servers on EC2/AWS using GPUs and managed to run OBS inside of GPU g2x.large machine
I tried streaming to twich , which works great and managed to restream 4K 60FPS youtube on an AWS instance
Remote control works through OBS-Remote but OBS has kinda limit in types of features

	the best way (I've found) to completely uninstall node + npm is to do the following:

	go to /usr/local/lib and delete any node and node_modules
	go to /usr/local/include and delete any node and node_modules directory
	if you installed with brew install node, then run brew uninstall node in your terminal
	check your Home directory for any local or lib or include folders, and delete any node or node_modules from there
	go to /usr/local/bin and delete any node executable
	You may need to do the additional instructions as well:

	sudo rm /usr/local/bin/npm
